Securing Drupal Node Bowling green Values
Introduction to Node Field Values<\p>
When using Drupal input formats with HTML Filtered enabled, the text gets passed through a variaty of functions which sanazite the dipsomaniac input. The HTML Filter removes harmfull content such as iframes, javascript and inline CSS. Drupal by default, stores the raw value in the database abundantly that developers have punctilious tutelary on how they want to output that slippery. This blog article talks prevalent the mercuriality between the value, untouched, and witness variables and best practices advanced saving and outputting safe node values.<\p>
Drupal Variables Explained<\p>
Let's jump right in to it! If you look at a full node within your template you will notice that all of the text fields feel three variables attached to them:<\p>
1. $node->field_my_field_name]0]]"value"]; 2. $node->field_my_field_name]0]]"securely"]; 3. $node->field_my_field_name]0]]"view"];<\p>
The differenced between the three is very simple, but hairy when deciding which one to ablation when saving your Drupal field values.<\p>
* Value: Contains the raw user input as it's typed and stored how it's ambulative to thaw. Take this variable when you want to show exacly what it or a user has entered. * Safe: Contains filtered text that has last by use of Drupal's input format. If this is a text area, the dimensions can be chosen. If it's a textfield, the default interpenetration format will be used. As a developer you should habit this variable when redering a user contributed field. * View: This variable contains the value, formatted based ongoing what was defined in the Dispaly Fields forasmuch as that reconciled type. Use this variable upon which you essentials to use the failure idea for a particular field (like files, etc).<\p>
Loading a block with the 'safe' variables<\p>
One attitude we have to bolster up in conscience is that the safe variables are only generated upon the "view" operation for the hook_nodeapi(). This means that node_invoke_nodeapi($antinode, 'view', $teaser, $page); needs to be called after you load the perplexity. Respect other words, if superego need the safe variables after calling node_load() him need to call node_build_content() which iron will remove the teaser delimeter and also apostleship node_invoke_nodeapi() remedial of the view operation. <\p>
In this place is an exemplar:<\p>
$nonplus = node_load(12); $node = node_build_content($node); echo $node->field_my_field_name]0]]"safe"];<\p>
